MEANS FOR FIEGULATING AND CONTROLLING GAS-SUPPLY.

No. 831,262. Specification of Letters Patent. Patented Sept. 18, 1906.

Applination filed Sept-ember 29, 1905. Serial No 280,662.

To all who/It 17/ 'umi (U/MlP/b. f IllBc it known that l. Vniiiir-w ll. (Kim, a l citizen of the United States, residhi r at (o l lumhus, in the county oi Fr iaklin and State i of Ohio, have invented wrtain new and usel ful Improvements in i'rlrarzs l'or Regulating l ol? the gas in the city-line.

and Controlling a (lash"upply; and I do herel 15 designaies a gate for shutting ell the by declare the Following to be a lull clear, as from the lield to the main controllingpipes and Y-eouplings, as shown, the flow of the gas is less l||l|)((l '(l.

13 designates a gate for shutting oil or reg lllating'lhe quantity of flow from the held. ll designates a similar gate for shutting A h and exact description 01' the invention sueh lJW'H 5 and 5 For the purpose of dIreetmg the as Wlll enable others skilled in the art to supply into the auxiliary or by-pass lines which it appertains to make and use the 16 riqn'esents gates in the auxiliary line same. between the short connectiitg-pipes H1.

The object ol' this invention is to provide 17 represents ordinary gages in the auxilan improved means for regulating and eoniary pipe (5 and 6 to indicate the pressure trolling the supply of gas to rim s and towns. from the held-line, and 18 represents similar In supplying gas to mics and towns it is important that thr supply be kept as nearly gages in the main controlling-line indicating uniform and constant as possible and that the pressure at which the gas is discharged into the city-hue. repairs may be made without cutting oil the 1.) rr nrstants eseape-pipes from the main sup 11y. controlling-line provided with a regulated 0 these ends the invention C(JHStSi'S in 1' he safety-valve 20 for relieving undue pressure combination and arrangement of parts herein the main (0Htl'GlllDg-llllG-S 5 and 5 21 designates pipes with provided eoeks 21" for discharging liquids that might aeeunlulate in the lnes 5 and 5.

22 re 'iressj-nts tanks containing water and oil into whieh the open ends of the by-pass lines 6 and 6" are submerged, said tanks being provided with suitable vents to carry off excess pressure, if necessary, in said auxiliary lines.

23 designates a filter interposed between the junction of the pipes 5 and 5 and the inafter described and elaiinerl n the HGOUIHPHHYJIHQ drawings, Figure l is a general or diagrammatic view of the apparatus, and Fig. 2 is a detail sectional view of a strainer used in the apparatus.

In the views, 3 designates thc field or primary supply-line, and 4- the city or controlled line. Between the lirldline and the i and connected two main controlling-lines 5 and 5 and two auxiliary or by-pass lines 6 and 6 In the main controllilw-lines I make loo )8 7 and 7.

lines is a series of diaphragmn-equahZ1ng or The filter is provided with a cocked vent 23*.

in practice the pipes .5 will preferably be laid on the lloor or ground and the pipes 6 and 6 directly above and parallel to them. The loops 7 and 7 will extend horizontally from the lines 5 and 5. 'lhe drawings, therefore, it will be understood, are merely diagrammatie.

The series of equalizers or pressure-reducing deviees S, F), and 1t) and 8 9, and 10 are graduated from high to low in power.

The function ol the loops 7 and 7 is to pressure-rmlueing devices 8, 9, and I 0 and 8", 9", and 10 'espectively, of ordinary eonstruetion each eonipanioned at each side by ordinary gate-valves 11. The equalizing devices 8, 9, and 10 and 8, 9 and 10 can be made in removable sections of pipe, so that they can be removed for repairing the equalizing device, the gates on opposite sides permitting the pipes to be closed for this purpose. The auxiliary or bypass lines 6 and 6 tap the field-line beyond the junction with the field-line of the two main controllingprovide suitable room for the settling of the lines 5 and 5*. The auxiliary lines are also llow between the first two pairs of reducing connected with the main controlling-1h]es at I devices without the oeeupation of extensive points between the series of pressure-reduel floor-spaee and the erection of a. more costly 111g devices by short pipes or by-passes 12, building. lnehned to the direction of motion of the gas The operation of the system 1s as lollows: through both hncs. By the use of inclined I If any of the equahzlng, or pressurwreducing devices in the main regnlatingdine needs repairs or attention it may be isolated by closing the companion gates and the [low ol' gas that ll wetl through it or them directed into one or both ol the by-pass lines. For example, it the pressurwreducing device {I should become deranged it can be isolated for repairs by closing its companion gates and opening the two right hand gates It) and then directing the gas through the by-pass line ti and the middle inclined pipe 11. at the lelt oi the devic ,l.

Should the srrcen 21')" become elwgged by the accumulation ol' Foreign things, it may be cleansed by closing the gate 15, opening the right-hand gate H3 in one or the other ol' the by-passes (i (5 and the cock in 33", thus establishing a back How through the screen and blowing out the clogging material.

The pressure ol the inllowing and outllowing gas can be noted at all times by watching the gages 17 and 1S and the reducing devices regulated accordingly.

Further, by this apparatus one ol' the pressin'e-iegulat'tirs can be lel't cut out and normally inactive to be put into use while a defective one is being repaired, thus insuring the maintaining of a nnil orni pressure in tilt controlled line.
